Activate pairing mode

If I read everything correctly in the manual I believe the light only stays on when the device is in the pairing mode. If the light flashes every second, the headset is on a call, if the light flashed every three seconds, it is in standby mode.
Standby mode: is when the Jabra BT160 is passively waiting for a call. When you 'end' a call on your mobile phone, the headset goes into standby mode.

Make sure your phone is bluetooth equipped.

You must first successfully pair the headset with your phone. The manual shows you how.....
1. Put the headset in pairing mode Make sure that the headset is on. Press the answer/end button and press the volume up (+) button at the same time, until a solid blue light comes on.
2. Set your Bluetooth phone to 'discover' the Jabra BT160 Follow your phone's instruction guide. This usually involves going to a 'setup,' 'connect' or 'Bluetooth' menu on your phone and selecting the option to 'discover' or 'add' a Bluetooth device.
3. Your phone will find the Jabra BT160 Your phone then asks if you want to pair with it. Accept by pressing 'Yes' or 'OK' on the phone and confirm with the passkey or PIN3 = 0000 (4 zeros). Your phone will confirm when pairing is complete. In case of unsuccessful pairing, repeat steps 1 to 3.

5.When prompted, enter the passkey “0000” (4 zeros) and press “oK” to complete the pairing
6. When the pairing pairing is successful the headset’s LED status indicator will begin flashing.

You should now be able to make and receive calls using your headset. To initially connect the headset to your phone, you may need to tap the CTRL Button once on the headset. iMPortAnt: if pairing is not completed within 2 minutes while the Pairing Mode is activated, the headset will return to Standby mode, flashing blue once every three seconds and you must start the Pairing process again from Step 2 above.

this happened to me too.. i googled a user manual for it.. if i recall it said, turn the headset power off, then once the phone is in pairing mode, hold the power button on the headset till the light stops blinking and becomes a solid blue light. then the headset is in pairing mode as well and your phone should find it

Pairing This was the second Bluetooth device I?ve used, and I had the headset paired in under 60 seconds once I had deciphered the instructions in the manual. When you press the call control and multifunction control buttons on the headset simultaneously, the M2500 goes into pairing mode. The standard way to get the Treo to pair is to click on the Bluetooth icon and basically follow the prompts: Turn Bluetooth on, make the device ?discoverable,? click on ?set up devices? and then ?Handsfree setup,? and the Treo will find the Plantronics headset. Once you?ve set up one Bluetooth device, you?re a pro. The only thing you need to know is the combination of buttons that puts a device into pairing mode. However, with the Plantronics M2500, I discovered an even easier method. Simply power up the Bluetooth headset while the Treo is on and you will be immediately prompted for the passcode, four zeros, if the devices are not paired. How cool is that? It saves many steps.
